Aircraft Image Acquisition in Passive Radiolocation

The problem of radio imaging small aircrafts in radio systems with inverse aperture synthesis is considered. The Abstract - In order to identify and assess the dimensions of small aircrafts, including unmanned aerial vehicles, obtaining their images is based on a specific model of target movement. Creating a one-dimensional radio image of an aircraft on a straight segment of trajectory and a two-dimensional radio image of a rotating object is possible. The problem is reduced to a system of linear equations to be solved by the regularization method. The applied method is classified as a high resolution one. The proposed technique can be used in passive radio engineering systems for aircraft identification.
